While that's certainly possible, I'd find it unlikely. Manufacturers (and Ford is no different) generally prefer a commonality of parts, especially in something as complex as engines. I'd expect that the issue is simply differing descriptions put out by different product teams describing the 'features' of each engine.
Now it's possible it's an ECU/software change to enable 'multi shot', but that seems unlikely to me as well. The Edge Sport doesn't have anything (on paper) than the Fusion. The mileage, power, acceleration (as far as we know) are all the same or worse than the Fusion Sport (as you'd expect from a heavier vehicle).
